Additional expected results: the large number of patients assessed for post traumatic symptoms might improve knowledge both of their prevalence and also of the trauma underlying MS. Even if it is not the primary aim of the study, assessment of the trauma load through the interview-based TAQ will lead to life-trauma evaluation which may be studied for their correlation with the onset of the disease and its emotional correlates. Moreover, in EMDR, associated traumas are defined and treated: given that sessions are video-recorded, their analysis (beyond the three sessions that will be reviewed for treatment fidelity) may add knowledge to the role of the trauma load in MS.
